EDAC/amd64: Split prep_chip_selects() into dct/umc functions
Call them from their respective hw_info_get() function. Avoid the
need for family/model-based function pointers.
Add the calls before reading hardware registers from the memory
controllers, since the number of chip select bases and masks needs to be
known first.
[ Yazen: rebased/reworked patch and reworded commit message. ]
